Ahockey puck of mass 0.450 kg is sliding across the ice. the puck is initially moving at 28 m/sec. however, because of the frictional force between the puck and the ice, the motion of the puck is stopped in 15.8 seconds. determine the magnitude of the frictional force.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
